The same practical idea can apply to any small village where a certain surname was common. You will probably also find out that there was a proliferation of the same surnames as well, most families. especially in the 18th century, had boys called William, James, Thomas John and Henry. In a family i was researching once however, one particular line repeatedly used lancelot, laurence and Richard. makes it so much easier.
I have alot of ancestry from the Lincolnshire villages around Boston and they all used the same names over and over. It is in these situations where the negative results help you to eliminate possibilities. If you are looking for James Smith marrying a mary Brown you may find a few in the same few years on the GRO marriage index, but by looking at the actual record you can discover occupations, whitnesses names and fathers names, and also sometimes there is a surviving marriage bond record which names other family members.
